What's the difference?

Question

What's the difference between worsted weight yarn and worsted medium weight yarn?

Answer 1

According to yarn standards.com, worsted comes in two weights, light and medium. One is thicker than the other.

For light garments (or heavy socks) light weight yarn is a popular choice. Also known as DK (for double knitting) or light worsted weight, this yarn is perfect for light sweaters, tank tops and light throws.

Worsted weight (also known as medium) is probably the most used weight of yarn. The biggest variety of yarn can be found in this weight, and it’s great for heavier afghans, sweaters and accessories like shawls, ponchos, pillows and handbags. There are many different color and texture variations in worsted weight yarns, so you can get many different looks from the same weight of yarn.

Answer 2

There truly shouldn't be any difference, as one size smaller from worsted is sport, and one size up is bulky. However, "worsted" sometimes gets tied together with sport, and "worsted medium" may be a little thicker, but shouldn't make a significant enough difference that you would need to worry about it.
